Remove static VrfEntryListener.isOpenStackVniSemanticsEnforced

VrfEntryListener defines a static isOpenStackVniSemanticsEnforced
which is set in the ctor via the IElanService. FindBugs flags this
as a violation although it technically is safe b/c VrfEntryListener
is a singleton. However statics in this manner aren't good practice.
Users of the static flag should instead inject and obtain the flag
from IElanService.

One user was the static FibUtil class. FibUtil was converted to a
singleton. It also had static methods that take the DataBroker
and IdManagerService. Thee services are now injected and the methods
changed to non-static to make it cleaner. All users of these methods
now inject the FibUtil instance.
